A Stress Measurement Method for Steel Strands Based on LC Oscillation
Advances in Materials Science and Engineering, 2018 The prestress loss is one of the main factors affecting the safety of prestressed concrete structure. While the detecting signals like sound and light are difficult to spread in steel strands, there is no effective method for prestress detection of the ...
